Description: A "teachable" on the construction of free-standing pyramids made "by folding a single piece of paper, with only a single piece of tape to hold them together...." This blog post goes on to include photos of a net, diagrams, and "things to investigate": maximizing sides; playing with heights, areas, and ratios; and silhouettes. A coordinator at a non-profit crisis hotline, Easter majored in computer science and music before earning his Master's degree in instructional design and technology, focused primarily on adult learning and performance improvement.
